Form of carbon black

2013-09-17

Formed by the carbon black, it is generally defined as inorganic pigments. Carbon black is a hydrocarbon gas by the incomplete combustion or warm solution made ​​of black powder-like substance. Because the different production processes, process conditions can be obtained through a variety of different properties of different products.

Microscopic structure of carbon black
Carbon black particles having a microcrystalline structure, carbon black, carbon atoms arranged in a manner similar to graphite, hexagonal plane composition, typically 3 to 5 to form a crystallite dimension such as carbon graphite crystallites each level , the carbon atoms are arranged in an orderly, while the adjacent carbon atoms are arranged between levels is unordered, so called quasi-graphite crystal.

The particle size of carbon black
Particles of carbon black pigment fineness as low as 5nm, in general, carbon black particles are not isolated, but several particles interspersed with each other through the carbon crystal layer to form branched chain. Different production processes can be obtained very wide particle size range of carbon black particles, lamp black production process the product obtained is relatively rough, and the gas production process is obtained black fine product.

Furnace black production technology available with almost all the particle size range of carbon black, carbon black of the same species, and its particle size is not exactly the same, showing a particle size distribution. In general, the smaller the particle species, narrow particle size distribution.
